Specification of Letters Patent. Application filed June 2,1906. Serial No. 319.952.

as usual, provided with two apertured lugs 67 at its front ends T0 all whom t 'may concern:

Be it known that I, GEORGE W. KING, a citizen of the United States, residing at Marion, in the county of Marion and State of Ohio,y have invented certain new and useful Improvements in Chain-Buckets for Dredges, of which the following is a specification, reference being had therein to the accompanying drawings. j

This invention relates to chain-buckets for dredges, and has for its object to provide a construction of the buckets of which the dredging-chain is composed whereby said buckets are strengthened and rendered more efficient and whereby their connections with each other are rendered more secure. l

To these ends the invention consists in certain novel features, which I will now proceed to describe, and will then particularly point out in the claims.

In the accompanying drawings, Figure 1 is a front elevation of a bucket embodying' my invention in one form. Fig. 2 is a side elevation of the same. Fig. 3 is a detail view of the j ournal-pin employed to connect the adjacent buckets. Fig. 4 is a detail sectional to receive a journal-pm connected. This pin is provided near each end with transverse slots 69, located on opposite sides thereof. An aperture 70 is formed through each lug, so as to intersect themain aperture 7l of said lug through .which the journal-pin 68 passes. Into the aperture 70 is fitted a locking-pin 72, having one of its sides flattened and tapered, as indicated at 73, so that when aperture 70 its flattened side will bear the bottom of one of the grooves 69 in the journal-pin 68, and thus clamp said pin in position. The locking-pin 72 is held in place by means of a screw-plug 74, which screws into the upper end of the aperture 70, which is threaded to receive said lug.

The construction just described provides a Erm and effective fastening for the journalpin free from all projecting parts, and therefore not subject to wear. The slotting. of the journal-pin -on both sides permits it to be 'turned when one side is worn, so as to bring the unworn side into bearing relation with view of the same, taken on the line a: of Fig. the sleeve of the next bucket or such other 3 and looking in the direction of the arrows. part of the chain as may fit thereon.
